Hi, I am a speech therapist who works with children. It sounds to me like your child is developing fine at this time. If she is using a few words that sounds age appropriate. Kids typically use a few words between 12-18 months and then begin producing approximately 20-50 words with meaning between 18-24 months. So I would suggest if you don't see an improvement in the next 3-6 months to consult a speech therapist for an evaluation. Hope this helps.
